Self‐Assembly: Dynamic Self‐Assembly of Homogenous Microcyclic Structures Controlled by a Silver‐Coated Nanopore (Small 25/2017)

In article number 1700234, Yi-Lun Ying, Yi-Tao Long, and co-workers, demonstrate that a well-defined silver-coated nanopore electrode acts as a “rocket” which can electrochemically manipulate silver ions diffused from the tiny opening of the nanopore. As a result, the confining electrochemical effect of the nanopore electrode guides the self-assembly of AuNPs in the microscale highly homogeneously and with good reproducibility. The size distribution of the micro-cyclic structures is consistent with the electrokinetic diffusion profile of silver ions.
